One of the processes associated with aging is progressive shortening of telomeres, DNA-protecting structures at the ends of chromosomes, like the plastic tips on shoelaces.  Each time a cell divides, its telomeres get shorter. Eventually, the cell can’t replicate anymore and dies or becomes senescent. However, telomerase can keep the length of telomeres intact, even after cell division.  Now, a study from researchers at University … Continue reading Male hormone reverses cell aging, increases telomere length, in clinical trial.
